Samples of fresh basalt were collected from Axial Seamount's caldera floor.  When fresh, the outer surface of the rock is glassy due to the very rapid cooling and crystallization that occurs when the hot lava comes in contact with the 2oC seawater.  This glass - known as obsidian - is very sharp and crumbles easily.

ROPOS collects vent chimney sample

The thermistor array will be deployed at the base of the hydrothermal vent Mushroom, on the lower right side of this image on top of the yellow incubators.

The thermistor array connected to the computer and power supply.

Live Visions 13 show with John Delaney and Mary Miller from the Exploratorium in the museum's Observatory Gallery on July 30, 2013.

This 90 cm, ~100 lbs. chimney was collected from the base of the El Guapo sulfide chimney at the International District Hydrothermal Vent Field on Axial Seamount (ROPOS Dive 1617).  (Photo by Leslie Sautter)

This resistivity-temperature probe was deployed in the 270°C hydrothermal vent called 'Escargot' at the summit of Axial Volcano in 2013. Resistivity is an analoge for chlorinity or "saltiness' of the hydrothermal fluids. Boiling is common in these venting environments, governing gas concentrations, metal deposition, and perhaps life. A cabled version will be installed in 2014 providing real-time 24/7 data. ROPOS dive #1618, VISIONS '13, Leg 3. Photo credit: NSF-OOI/UW/CSSF.

This relatively small (<1 m) inactive chimney recently toppled over, becoming an excellent sample for collection. (ROPOS Dive #1617, VISIONS '13, Leg 3) Photo credit:  OOI-NSF/UW/CSSF

Students Brendan Philip and and Cody Turner work with Professor Julie Nelson in the computer lab.  They are monitoring the temperature and salinity profiles created during the downcast of the CTD to determine the depths for triggering Niskin bottles for seawater collections.

An at-sea tradition is to send styrofoam cups and wig-heads (usually embellished with stylistic artwork) down to the depths so that the overwhelming pressure in the deep sea compresses the objects into miniature versions. (Photo by Leslie Sautter)
